Ciatim 221 shelf life. Performance properties and characteristics

For many car enthusiasts, the choice of lubricant for servicing their car is quite acute. This is understandable when you consider that everyone wants to have a universal grease at hand, suitable for servicing most parts of the car in all weather conditions.

Now many of the lubricants produced in the Soviet Union in accordance with GOST acquire a certain aura of mystery in the minds of many people. It is believed that the strict standards and careful quality control that each manufactured product underwent in those years ensured consistently high quality. This fully applies to the CIATIM 221 grease.

The very name of the CIATIM grease (Central Institute of Aviation Fuels and Lubricants) connects this product with aerospace technologies in the minds of many car owners. Many of them believe that the scope of this wonderful lubricant is truly limitless.

However, is it really so?

Specifications

It is known that the working properties of any lubricant are primarily determined by its composition.

CIATIM 221 grease is made on the basis of silicone oil and a complex calcium thickener. It is known that organosilicon fluids maintain working properties over a wide temperature range.

The use of a thickener in greases significantly narrows the temperature range.

According to GOST, CIATIM-221 is intended for lubrication of friction units and mating surfaces "metal-metal" and "metal-rubber". Temperature characteristics of CIATIM 221 guarantee its effective use at temperatures from -60 to +150 ° C.

As you can see, the grease is frost-resistant and heat-resistant. It can operate both in the Far North and in hot climatic zones, and can be used in high-temperature equipment.

One of the components of CIATIM-221 are antioxidant additives, which prevent the material from rapidly losing its properties under the influence of atmospheric oxygen and high temperatures.

Silicone greases are chemically inert. They are not destructive to rubber and plastic parts.

One of the special properties that make CIATIM-221 a particularly popular material is the retention of a low effective viscosity at significant negative temperatures. This allows the grease to be used in high speed bearings and precision instruments down to -60 ° C.

CIATIM-221 does not contain water and does not dissolve in water, retains its properties in boiling water. But, at the same time, it is very hygroscopic, therefore it absorbs moisture well from the atmosphere. In this case, the lubricant is compacted and becomes ineffective at low temperatures.

Due to its high hygroscopicity, the lubricant should be stored only in a sealed, tightly closed original container. Under such conditions, the properties of the material can be maintained for several decades.

A remarkable feature is that even after complete melting during heating and subsequent cooling, CIATIM-221 fully restores its original properties.

Advantages and disadvantages

The composition and features of the lubricant production determine its main advantages and disadvantages.

Main pluses:

• Wide operating temperature range from -60 to +150 ° С
• CIATIM 221 operates at very high bearing rotation speeds
• Chemical inertness makes the grease compatible with plastics and elastomers
• The grease is characterized by low volatility, therefore it can work in a vacuum
• CIATIM-221 grease is inactive and harmless to the human body, does not irritate the skin and mucous membranes

We see that CIATIM 221 grease can operate in a very wide temperature range.

If there are many analogues at the upper limit of the temperature range (+150 ° C) today, then in terms of frost resistance (-60 ° C) it has very few competitors.

Minuses:

• The main disadvantage of the lubricant is its low bearing capacity compared to traditional materials, which is determined by the silicone base oil used for the base.
• In addition, organosilicon fluids operate ineffectively in the metal-to-metal tribological system, since they do not form a strong lubricating film on the friction surface that protects against wear. As a result, silicone greases exhibit a lubricating effect only at high sliding speeds when the hydrodynamic lubrication mode is implemented.

Application

The technical characteristics of the CIATIM-221 grease indicate its low bearing capacity and ineffective operation in metal-metal steam. For this reason, the material has a limited scope.

However, in the field of equipment operation at low temperatures and high rotation speeds, CIATIM-221 has few competitors.

Examples of typical applications:

• Bearings for electric machines with a speed of up to 10,000 rpm
• High-speed instrumentation and control systems
• Aircraft Aggregate Bearings
• Friction units and mating surfaces "metal-rubber"
• Equipment assemblies operating in a vacuum
• Unloaded nodes of outdoor equipment operating at low temperatures
• Operation at temperatures down to -60 ° C and low volatility in a rarefied atmosphere (vacuum) have allowed service departments to lubricate aviation components with this grease for many years.

Analogs TSIATIM 221

Among all the variety of lubricants, it is difficult to lubricate CIATIM 221 with an analogue in all operating parameters at the same time. However, when it comes to a specific application, it is very rare that all properties are required at once.

In most cases, a replacement for CIATIM 221 is looked for when it comes to heat resistance or frost resistance, as well as the ability of a lubricant to work in a vacuum.

According to these parameters, you can select several materials of both domestic and foreign production.

Advantages:

• Affordable price
• Works at very high speeds under heavy loads

Flaws:

• Low upper limit of operating temperatures

Which is better - Litol 24 or CIATIM-221?

This question can often be heard from newbie car owners. However, the very formulation of the question is fundamentally wrong and incorrect. This is tantamount to asking which is better - bread or cheese.

Although Litol-24 and TsIATIM-221 belong to greases, they were originally created for different purposes. Litol was developed as a universal grease for ordinary conditions of use, and CIATIM - as a special thermo- and frost-resistant grease.

The first of the materials is made on mineral oil and is effective in the range of medium loads and speeds, but it can take significant loads. CIATIM-221 synthetic silicone grease cannot withstand significant loads, but is used in high-speed bearings.

LITOL-24 works perfectly in a metal-metal friction pair, but is aggressive towards plastics and rubbers. CIATIM is inert in polymers and elastomers, but cannot work in a purely metallic friction pair.

In a word, these are completely different products with their own pros and cons. And each of them has its own area of ​​application.

Thus, when choosing CIATIM-221 as a lubricant for your car, you need to clearly understand where it will be most effective and where it will not cope with the operating conditions. For loaded assemblies or metal-to-metal friction pairs, it is better to use other lubricants.

When absorbed by moisture, it compresses, has low antiwear characteristics, is inert to rubber and polymer materials. It is efficient at a residual pressure of 667 Pa, in the temperature range from -60 o C to +150 o C.

The most demanded parameter of CIATIM 221 lubricant is a rather high temperature of product application - up to 150 ° С. Low values ​​of effective viscosity at negative temperatures are no less important. Due to this characteristic, the grease does not thicken much with the onset of cold weather and can be operated even down to minus 60 ° C.

Another significant performance indicator of TsIATIM-221 grease is its inertness to rubbers and plastics. The reason for this behavior of the CIATIM-221 grease is an organosilicon fluid as an oil base for the grease.

Functional analogs

The following can be noted as analogues in terms of functional purpose from products of Russian and foreign production:

• Mobil SHC - slightly wider temperature range, hygroscopic in water and remains stable against oxidative reactions;
• HUSKEY HVS-100 Silicone Grease and CIATIM-201 grease - protects the aggregate bearings of aircraft from oxidation, wear and tear, units of friction pairs and propeller pairs in the range of -60 / + 120 degrees, the composition also contains no mechanical impurities;
• O-Grease - recommended for use in the Far North, often serves as a single lubricant;
• Mobiltemp - suitable for preservation and lubrication of devices operating in the open air, friction units and mating surfaces are reliably protected from moisture and corrosion, however, product leakage is not excluded due to its low mechanical stability;
• Aeroshell "Grease15" - protects aircraft bearings friction units from the possibility of corrosion in the temperature range from - 73 to +232 degrees Celsius;
• Unirex S2 - the upper limit of the operating temperature is 200C, and the dropping is 280 degrees, it is resistant to oxidation and is characterized by anti-corrosion properties, it is suitable for the lubrication of electric machines of control systems and instruments, but requires preliminary clarification of compatibility with rubber and polymer materials, since softening and loss of shape of the seals.

CIATIM-221 grease is insoluble in water, hygroscopic, and remains stable even when boiled. this grease has found a field of application in electric machines at temperatures from minus 60 to 150 degrees, in addition, in electric motors and rubber-metal friction pairs. When absorbed by moisture, the seals have low antiwear characteristics. Before applying the lubricant, the assembly should be cleaned of previous materials. The antiwear properties of the grease are quite high.

Perspective of application

Tsiatim-221 grease demonstrates outstanding mechanical and thermal stability. Even after 1000 hours of operation at a temperature of +150 ˚С, it hardly changes its physical and chemical properties and practically does not evaporate. And if the thermal effect lies in the limit up to +80 ˚С, and the speed limit is up to 2500 rpm, then the performance of the product increases significantly.

The standard assumes the use of a lubricant in direct contact with aggressive media, but in comparison with modern materials, the chemical stability of Ciatim-221 is satisfactory. Therefore, it is advisable to use it only in contact with slightly aggressive vaporous media. At the same time, due to its low chemical activity, high thermal-oxidative stability in a wide temperature range and an increased lubrication interval, it actively displaces outdated grease VNII NP-242 and 1-13 in electric machines. In bearing assemblies of electric motors and electrical equipment, operating at a speed of up to 6000 rpm, it provides a stable antifriction, antiwear and anticorrosion effect up to 2000 ÷ 3000 hours.

Due to the polymethylsiloxane base, the product demonstrates excellent and stable performance at low and high temperatures and in humid air, under vacuum conditions and at normal atmospheric pressure. Therefore, Tsiatim-221 is of particular interest for servicing friction pairs of instrumentation and navigation devices, lightly loaded mechanical transmissions and rolling and sliding bearings of various aircraft.

The grease is inert to aging and exhibits good colloidal stability. Due to this, when stored in a manufacturer's container, it fully retains its rheological and protective properties, and in batch-type mechanisms it can be used as a permanent lubricant. Taking into account the ratio "price / quality", it is the most promising product for modern engineering.

High-temperature grease CIATIM 221 is used in a wide range of alternating temperatures of operating media from 60 to +150 degrees.

Application:

CIATIM 221 grease is most often used in servicing bearing assemblies of electric motors, regulation and control units, various devices, incl. and operating under vacuum conditions at a pressure of 0.0066 atmospheres.

For preventive maintenance of drying chambers, computer equipment, for lubricating ball bearings in fans during operation at high and low temperatures.

The grease does not dissolve in aqueous solutions, has high hygroscopicity and does not lose its working qualities even when exposed to steam and boiling water. When absorbed by vapors or water, it compresses.

CIATIM 221 is inert to rubber polymers and plastics, does not cause their swelling and destruction, and has unique performance characteristics.
